Product Specifications

Spec Highlights

Time-lapse etching

15 / 30 / 45 min

The catalog shows surface comparison images at 15, 30, and 45 minutes.

Ultrasonic cleaner

30 mins

Place the etching container in the ultrasonic cleaner for 30 minutes.

Rinse cycle

2 minutes

Rinse the crown in cold running water for two minutes after etching.

Anneal

1150C / 2102F

Hold for 30 minutes, then cool slowly before removal.

Removal threshold

Below 200C / 392F

Remove the crown only after the cooling temperature drops below this level.

Key Features

Consistent Bond Strength Enhancement

Zircos-E Etching Liquid chemically activates zirconia surfaces to improve adhesion reliability with resin cements and porcelain materials.

Low-Damage Surface Conditioning

By reducing reliance on aggressive mechanical roughening, it helps minimize microcrack risk and supports long-term restoration stability.

Biocompatibility-Conscious Formula

Developed with medical material compatibility in mind, the formula supports safe clinical workflows and broad protocol interoperability.

Precision Surface Preparation

Uniform control of surface energy and microstructure improves reproducibility and reduces variability between restorative cases.

Indications

Optimized for precision adhesive restorations, including veneers, inlays/onlays, and Maryland bridges.

Process Conditions

Observation checkpoints

15 min / 30 min / 45 min

The catalog explicitly compares these etching stages with before/after photos.

Ultrasonic phase

30 mins

The product workflow emphasizes a 30-minute ultrasonic cleaning phase for consistent treatment.

Anneal condition

1150C / 2102F for 30 mins

After rinsing and drying, the crown is annealed before porcelain layering or glazing.

Safe removal

Below 200C / 392F

The catalog instructs removing the crown only after the annealed piece cools below this threshold.

Surface treatment

The theoretical background pairs activation, micrographs, and low-temperature degradation comparisons.

Process Steps

Use the product as a controlled mid-workflow treatment rather than a general surface cleaner.

1

Protective setup

Wear safety goggles, gloves, and protective clothing before opening the working box.

2

Load the zirconia crown

Open the etching liquid container inside the box and place the sintered zirconia crown into the liquid using plastic forceps.

3

Ultrasonic treatment

Move the container into the ultrasonic cleaner and run the cleaner for 30 minutes.

30 mins

4

Rinse and steam clean

Remove the crown, rinse it in cold running water for two minutes, then steam clean it.

2 minutes

5

Anneal the crown

Increase temperature to 1150C / 2102F, hold for 30 minutes, and cool slowly before removal below 200C / 392F.

1150C / 2102F

6

Finish the restoration

Layer porcelain in the usual way or glaze directly for a full-zirconia crown.

Process Schedule

Treatment schedule

Scan -> CAD / CAM -> Design -> Milling -> Sintering -> Adaptation -> Zircos-E Etching -> Glazing

The catalog positions Etching Liquid as a mid-workflow treatment between adaptation and glazing.
